Young George Harrison (15), John Lennon (18) and Paul McCartney (16) playing together as kids in 1958 before becoming The Beatles two years later.
Looking at George, he doesn't look old enough to shave. They were playing in Hamburg, Germany two years later.
It seemed that the Beatles were together for ages - they seemed perpetually on the radio. But in reality, the band only lasted ten years.
Meanwhile, their contempories, The Rolling Stones forming two years after The Beatles got their name, are still rolling 62 years later.
How do they do with all their drugs, heart attacks (and Keith being Captain Jack Sparrow's dad)?
The band claim that Mick just calls them up, says there's another tour, and they're still up for it!
They are touring North America again in 2024.
They're comfortable admitting their fan base is long in the tooth too - their official sponsors are the AARP - the American Association of Retired Persons.
Although younger than them, I wish I had even half their stamina...
